WIRE-'BARBING MACHINE.

SPECIFICATION forming part of Letters Patent No. 325,311, dated September 1, 1885.

Application filed July 6, 1885. (No model.)

To all whom, it may concern.-

Be it known that I, ALBERT J. Barns, a citizen of the United States of America, residing at Jolict, in the county of ill and State of Illinois, haveinvented certain new and useful Improvements in Wire-Barbing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure l is a plan view of the top of the machine. Fig. 2 is a vertical cross-sectional view of the machine on line 2 of Fig. 1, looking in the direction of the arrow. Fig. 3 is a detail perspective view of the several barbcutters and formers and guides, showing their position and relation to each other. Fig. 4 is a perspective View of a section of the barb strip as it would appear when a barb has been out and formed and a prod out and formed one on each of the two next succeeding barbs. Fig. 5 is a side view of the reciprocating strand-wire guide, showing it mounted on one of the barb-cutters on which it reciprocates, looking in the direction of arrow 2 of Fig. 3. Fig. 6 is a side view of the ratchet mechanism for operating the barb-strip feed-rolls; and Fig. 7 is a perspective view of a four-pointed fiat metal barb seated between a pair of ca-v bled strand-wires, it being the product of the machine.

This invention relates to certain improve ments in a machine for cutting, forming, and setting fourpointed fiat metal barbs between a pair of strand-wires afterward cabled together to hold them in place, and is designed to be certain improvements on the machine for said purpose for which Letters Patent of the United States were on the 19th day of May A.- D., 1885, granted to me and numbered 318,079, which improvements consist, principally, in the parts that operate the harbcutters, and in a reciprocating strandwire guide, and which improvements are fully set forth and explained in the following specification and claims.

Referring to the drawings, 13 represents the main bcdlrame of the machine mounted on suitablelegs, and upon which bed the working parts of the machine are properly arranged and supported.

B represents a secondary and elevated bed mounted on bed B, and arranged to support the stationary barb-cutters cl, (1, and h, barbst rip guides at and k, stationary strand-wire guide it, and reciprocating strandwire guide 5 E, in the manner represented in Figs. 1 and 2, and located with reference to each other as shown in Fig. 3.

S represents the drive-shaft of the machine, located in suitable boxes across the top of bed 6 B, near one end of the machine, and arranged to support cam c, crank-wheel Z, and large spur gear-wheel D, all rigidly secured thereto and located as shown in Fig. 1, and adapted to receive mot-ion by means of said spur-gear 6 meshing with a corresponding but smaller gear-wheel, A, secured to a twisteryoke, (shown at T, Fig. 1.) As the twister and spooler is no part of this invention no more of it is shown; but, however, it is necessary to use the machine in conjunction with a twister and spooler, in order to cable the strand-wires and coil the cable strandwires on a suitable spool.

H is a lever fulcrumed at H to upwardly- 7 extending lugs m m of bed B, and arranged longitudinally in the machine with bed B. The movable end H of said lever is provided with a roller-wrist, J, studded to its side and adapted to traverse the channel a of cam-wheel c, for working that end of said lever. This lever H is provided with the integral upper portion terminating in the head H, for holding the barb-cutters d" The lever H is provided with a barb cutter, h, set in its body about midway between its fulcrum and its working end. \Vhen the cam 0 moves the working end of said lever downward, it will cause cutters d d to shear with cutters d (1, set in bed B, and when said lever moves upward it will cause cutter h to shear with permanent cutter h, set in said bed.

The cutters d (1 are adjustahly secured to bed 13 by means of a suitable cap-plate and set-screws, (shown in Figs. 1 and 2 at an) and cutter h is adjustably secured to said bed by means of cap-plate a and suitable setscrews, as shown in said figures. The cutters d d are also adj ustably held in cutter-head H by means of suitable cap-plates and setscrews, as shown. 10o

F F are a pair of feed-rolls secured on shafts S S, which are properly boxed in the housings F F, (see Figs. 1 and 2,) and are rotated intermittingly to feed forward the barb-strip V, passing between them, by means of crankwheel Zof shaft S, through the medium of pit man I lever I ratchet-wheel R, and pawl P.

On bed B, and immediately in front of and between feed-rolls F F, is located a guide, G, held by a suitable cap-plate, which guides the barb-strip V from said rolls to and between the several cutters, and between the strandwires WV W, as shown in Figs. 1, 2, and by dotted lines in Fig. 3. A pair of barb-stripadjusting guides, k and n, are set in bed B, as shown in Fig. 1, and are adjusted by means of set-screws to bring them against either edge of the barb-stri p to more properly guide and hold it between the said cutters. Guide a is shown in full lines in Fig. 1, and guide 7c by dotted lines, and their relative position with the barb-strip and cutters is shown in Fig. 3. The strand-wires W W" are arranged to cross the machine over bed B and between cutters d d and d (Z one on either side of the barb strip V, the lower wire, WV, which passes under the barb-strip, being guided by means of the recessed guide t, wh ch is set bet-ween cutters d d, as shown in Fig. 3, and strand-wire WV, which passes over the guide-strip, is guided by passing in the channel E of the reciprocating guide E, as shown in said figure, and also in Fig. 2. This reciprocating guide E rests on cutter d, as shown in Figs. 3 and 5, and is properly held in position by means of a capplate, a. (Shown in Figs. land 2.) Said capplate is provided with a slot, a, immediately over guide E, through which a stud, a", of said guide passes. Said guide E is reciprocated by means of the lever L, fulcru med at '1, one end of which lever connects with said stud a", and its opposite end is provided with a wristroller to operate in the waved cam-channel c of cam c. Said guideEis timed so as to move forward to separate the strand-wires W W at the instant the barb-strip is fed forward between them, so it will be certain to enter between them; and it recedes after the barbstrip is fed in and the barb is formed by the cutters, so that the strand-wires may close upon the barb to hold it in, as shown in Fig. 5.

The reciprocating guide E is shown in Fig. 3 as having two channels, E. It is so formed that when one channel is worn out it may be reversed and the other one used. The strand wires WV IV pass from said guide to a twister and spooler, a portion of which is shown at T, Fig. 1, by means of which they are cabled together to grasp and hold the barbs as they are, formed. When cutters d d descend,they will, in conjunction with cutters d d, cut and form the two downwardly-extending prods of the barb, beginning to shear at their point, and bend them down to the proper angle. The forward upper prod will be bent upward by means of its heel resting on shoulder g of cutler d, the rear upper prod having been cut and formed in advance by the previous upward move of the lower cutter, h, in conj unction with stationary cutter h. Thus the rear upper prod of a next succeeding barb is being cut and bent upward when cutter h ascends,

and the next downward move of cutters d d",

in conjunction with cutters dd, cut and form the remaining prods by cutting on the dotted lines shown in Fig. 4, and each downward stroke of cutters d d finishes a barb and leaves it between the strand-wires, as shown in Fig. 7..

I claim 1. In the wire-barbing machine shown and described, the cutters d, d, (1*, d, h, and 71, arranged in combination with each other and with bed B and lever H and means for op erating the lever, whereby at each descent of cutters d (1 three prods of a barb are cut and formed and a barb severed from the barbingstrip and seated between a pair of cabling strand-wires, and at each ascent of said levercutter h it, in conjunction with stationary cutter 71-, cuts and forms the rear upper prod of the next succeeding barb, substantially as set forth.
